  "term": "Relative retention",
  "field": "Chemistry",
  "definition": "The ratio of the adjusted retention time or volume of a substance to that of a standard substance, obtained under identical chromatographic conditions. This value provides a standardized measure of a compound's retention behavior, independent of factors like column length or flow rate. A relative retention value greater than 1.0 indicates that the substance is retained more strongly than the standard.",
